[Github] Bump actions script version to v7 (llvm#131471)

This patch bumps the actions script version in the issue-write workflow
to v7. This was done before but rolled back due to errors as there were
breaking changes in v5
(https://github.com/actions/github-script#breaking-changes-in-v5). This
was reverted in f984b47.

This patch makes the necessary changes to prevent job failures.

Fixes llvm#130211.
